MEANS FOR OPERATING PLANTER-MARKERS.

Specification of Letters Patent.

Patented March 16, 1909.

Application led October 3, 1908. Serial No. 456,098.

adapted to have said markers moved by hand from one side of the machineto the other when turning the planter at the end of a row preliminary7to recrossing the field.

The present invention provides operating means whereby the marker may bethrown from one side of the machine to the other automatically at thetime of turning the machine at the end of a row.

The invention contem Jlates clutch devices between the ground w ieelsand the axle, whereby when turning the machine the wheel describing thelarger circle operates to rotate the axle so as to move the marker fromone side of the machine to the other when the operating fearing isthrown into clutched engagement by the shifting of a lever.

The invention further contemplates o positely disposed segment gearsconnecte for simultaneous movement and mounted upon a shaft to movethereon and to turn therewith, said shaft having the marker connectedtherewith. A second shaft arranged. at a right angle to the shaftprovided with the segment gears, is supplied with a gear wheel designedto mesh with either one of the segment gears, and with a ,second gearwheel in meshing relation with a gear wheel fast to the axle andreceiving power therefrom.

For a full understanding of the invention and the merits thereof andalso to acquire a knowledge of the details of construction and the meansfor effecting the result, reference is to be had to the followingdescription and accompanying drawings.

l/Vhile the invention may be Vadapted to different forms and conditionsbychanges in the structure and minor details without departing from thespirit or essential features thereof, still the preferred embodiment isf shown in the accompanying drawings, in

which yshown in Figs. 2 and 3.

Figure l is a plan view of a portion of a planter provided with a markerand co erating gearing embodying the invention. 4 ig.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

The invention is adapted to be applied to any make or type of planterprovided with a marker adapted to be thrown from one side f of themachine to the other.

In the drawings, the numeral 1 indicates the main frame of the planter,2 the axle, 3

the ground wheels loosely mounted upon the arms or spindles of the axleyand 4 clutch or ratchet devices between the ground wheels and the axle,whereby the' latter may be:

rotated at the end of a row bymeans of the wheel describing the largercircle.

The clutch devices 4' may be of any construction so long as they serveto permit motion from the ground wheels to the axle and admit of saidground wheels turning backward without imparting any movement to theaxle. f

A shaft 5 is arranged at a right angle to the axle 2fand is mounted insuitable bearings and is provided with'the marker and with connectedsegment gears 6 and 7. The shaft 5 is centrally disposedwith referenceto the width of the machine so that the marker may extend a likedistance from each nected by means of a sleeve y8, one. end of which isextended and provided with an annular grooveV to receive the forked endof a shipper lever 9.- The shipper lever 9 may be of any construction orarrangement and preferably consists of a footlever of such formation andlocation as kto, be actuated by a foot of the driver, thereby leavingthe hands free for management of the team and other parts of themachine.

A gear wheel 10 fast to the axle 2 is in mesh with a gear wheel 11 fastto a shaft 12 paralleling the axle and located beneath the same. A gearwheel 18 formed with or connected to the gear wheel 11 is adapted tomesh with the teeth of either of the segment gears 6 or 7 according tothe position of the lever 9. The segment gears 6 and 7 are of suchconstruction and arrangement that when the marker is in operativeposition, the segment gear last in mesh with the gear Wheel 13 clearsthe latter, thereby permitting continued rotation of the axle and shaft12 without disastrous results. The other segment gear is in position sothat upon operating the shipper lever 9 it will engage with the gearwheel 13 and thereby serve to move the shaft 12 to throw the marker tothe opposite side of the machine and just prior to said marker reachingthe limit of its throw, the segment gear clears the gear wheel 13,thereby permitting the axle and shaft 12 to continue rotating withoutbreaking or straining any of the parts associated with the markingmechanism.

The marker comprises an arm 14 and a runner 15. The arm 14 is connectedto the shaft 5 in such a manner as to have a limited pivotal movement.As shown, a yoke 16 is clamped to the shaft 5 and braces 17 arepivotally connected to the ends of the yoke 16 by means of a bolt 18.The inner end of the arm 14 is pierced and the bolt 18 passestherethrough. The outer ends of the braces 17 are clamped or otherwisesecured to the arm 14, thereby steadying the same in the plane ofmovement of the marker when thrown from one side of the machine to theother. A spring 19 connects the arm 14 with the rear end of the shaft 5so as to hold the marker in proper position when backing the machine forany purpose.

When the machine reaches the end of a row and is about to be turned, theshipper lever 9 is operated to throw one of the segment gears 6 or 7into position to engage with the gear wheel 13. As the machine turns,the wheel traveling on the larger circle serves by means of the clutchor ratchet mechanism to rotate the axle 2 which by reason of the gearwheels 10l and 11 rotates the shaft 12 and the gear wheel 13, the latterin turn causing, the shaft 5 to rotate so as to Y throw the marker fromone side of the machine to the other.

It is to be understood that after the marker passes the perpendicular,it may descend by gravity, hence when the segment gear in mesh with thegear Wheel 13 clears the latter, the marker will drop until the runner15 rests upon the ground.

It is to be understood that the operating gearing, after serving tothrow the marker from one side of the machine to the other,automatically throws itself out of action,

thereby preventing injury to any part of the mechanism co eratingtherewith.

Having thus escribed the invention, what is claimed` as new is:

1. In a planter provided with a marker ada ted to be thrown from oneside of the mac ine to another, the combination of a power driven shaft,a second shaft arranged substantially at a right angle to the powerdriven shaft and having the marker connected therewith to be movedthereby from one side of the machine to the other, connected segmentgears mounted to turn with and to move on said second shaft, acoperating gear fast to said power driven shaft and adapted to mesh witheither one of the segment gears, and means for moving the segment gearsto bring one into position to mesh with the said gear wheel fast to thepower driven shaft, the segment gears being of such construction andarrangement as to automatically clear the coperating gear wheel afterthe marker has passed the dead point in its movement and prior toreaching the ground.

2. In combination, a shaft provided with a marker, spaced segment gearsmounted on said shaft to turn therewith and move thereon, said segment`gears being connected to move in unison, a shipper lever for moving thesegment gears, a power driven shaft, and a gear wheel fast to the powerdriven shaft and extending into the space formed between the saidvsegment gears to mesh with one or the other thereof.

3. In a planter, the combination of an axle, ground wheels mountedloosely upon said axle, a clutch mechanism between each ground wheel andaxle, a second shaft provided with a marker, segment gears mounted uponsaid second shaft to turn therewith and to move thereon, an intermediateshaft between the axle and said second shaft and geared to the axle, anda gear wheel fast to said intermediate shaft in position to mesh witheither one of said segment gears to automatically'throw the marker fromone side of the machine to the other, the segment gears having their endportions overlapped and arranged to admit of the active segment gearsclearing the drive gear prior to the marker shaft reaching the limit ofits movement in either direction.

In testimony whereof we affix our signatures in presence of twowitnesses.
